A 6-year-old boy tumbled out and landed in the street. A 5-year-old ended up in an apartment building parking lot.

"He hit his head on the back of my car and then he fell to the ground," Seymour said of the 5-year-old.

Both were in serious condition when they were airlifted to Albany Medical Center, police said. Their names and injuries were not released.

"Although the investigation is continuing, the incident is considered a tragic accident and no charges are pending," police said.

WNYT reported that after the boys fell out, the bounce house continued to float in the air, eventually landing in the field behind a local school.

Neighbors told WNYT that the man who owned the bounce house felt terrible about what happened. His children were not the ones playing on it at the time.

"I actually watched the fellow that put it up and he staked it and he did everything correctly," Stephanie Hansen, who called 911, told the station. "All the kids were having fun until they screamed to me to come down and I saw that."
